Technical Field

[0001] The utility model relates to the technical field of anti-blocking fire pump adapters, in particular to an anti-blocking fire pump adapter. Background Technique

[0002] At present, with the continuous increase of high-rise buildings, the fire problem is becoming increasingly serious. The fire pump adapter is a self-provided fire-fighting facility supporting high-rise buildings, used to connect fire trucks and mobile pumps to convey fire-fighting water to the building pipe network. The fire truck sends water through the interface of the adapter to the fire-fighting water supply system inside the building to pressurize, so that the indoor fire hydrants or other water supply system fire-fighting devices inside the building can obtain sufficient pressure water sources to extinguish fires on different floors.

[0003] The existing fire pump adapters are usually connected to the water supply systems of fire-fighting equipment such as automatic sprinkler systems or fire hydrants in buildings, which solves the problems that it is difficult for fire trucks to extinguish fires after a fire occurs in the building or the fire-fighting equipment indoors cannot extinguish fires due to lack of sufficient pressure water sources.

[0004] However, when there is a long-term flow of water inside the existing fire pump adapter, there are many impurities in the water flow. After a long time, it is easy to cause blockage problems inside the adapter body, and it is impossible to dredge the blockage well. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an anti-blocking fire pump adapter, which solves the problems that when there is a long-term flow of water inside, there are many impurities in the water flow.

The output pipe and the sewage discharge pipe are fixedly connected by bolts, which is convenient for disassembly and facilitates the cleaning of the first filter screen.

[0008] Preferably, a flange is installed at one end of the output pipe close to the second gate valve.

[0009] Preferably, an anti-flow unit is arranged inside the adapter body.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] When there is long-term water flow inside the existing fire pump adapter, there are many impurities in the water flow. After a long time, it is easy to cause blockage problems inside the adapter body, and it is impossible to dredge the blockage well.

[0020] In view of this, the present utility model provides an anti-blocking fire pump adapter. Through the cooperation between the sewage discharge pipe, the first filter screen and the second filter screen, after the adapter body is connected, the water flow passes through the adapter body and flows into the output pipe, and then continues to flow into the sewage discharge pipe. The first filter screen inside the sewage discharge pipe blocks the impurities, and then continues to flow along the other end of the output pipe, and then is blocked by the second filter screen for the second time, avoiding blockage of the adapter body caused by excessive impurities. The second filter screen can be backwashed through the backwashing part to avoid excessive impurities on the second filter screen and affect the filtering effect. The sewage discharge pipe and the output pipe are fixedly connected by bolts, which is convenient for disassembly, and the first filter screen can be disassembled and cleaned.

[0021] Those skilled in the art shall connect the components in this case in sequence. For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are well-known techniques in this field. The following mainly introduces the working principle and process.

[0022] Embodiment 1: As Figures 1-4 can be seen, a fire pump adapter for preventing blockage includes an adapter body 1. Two covers 11 are threadedly connected to the surface of the adapter body 1. A valve cover 12 is threadedly connected to the surface of the adapter body 1. A filtering device 2 is arranged below the adapter body 1. The filtering device 2 includes: an output pipe 21, which is communicated with the bottom of the adapter body 1; a sewage discharge pipe 22, which is communicated with the bottom of the output pipe 21; a first filter screen 23, which is fixedly connected to the inner wall of the sewage discharge pipe 22; a second filter screen 24, which is fixedly connected to the inner wall of the output pipe 21; a backwashing part 25, which is arranged on the outer wall of the output pipe 21. Among them, by opening the cover 11 to connect the water pump, the water flow enters the output pipe 21 through the inside of the adapter body 1. The impurities in the water flow are filtered by the first filter screen 23 and the second filter screen 24 to prevent the pipeline connected to the adapter body 1 from being blocked. The second filter screen 24 is backwashed by the backwashing part 25;

[0023] In the specific implementation process, it is particularly worth noting that after the adapter body 1 is connected, the water flow passes through the adapter body 1 and flows into the output pipe 21, and then continues to flow into the inside of the sewage discharge pipe 22. The first filter screen 23 inside the sewage discharge pipe 22 blocks the impurities, and then continues to flow along the other end of the output pipe 21, and then is blocked by the second filter screen 24 for the second time to prevent the adapter body 1 from being blocked due to excessive impurities. The second filter screen 24 can be backwashed by the backwashing part 25 to prevent excessive impurities on the second filter screen 24 from affecting the filtering effect. The sewage discharge pipe 22 and the output pipe 21 are fixedly connected by bolts, which is convenient for disassembly, and the first filter screen 23 can be disassembled and cleaned;

[0024] Furthermore, the backwashing part 25 includes: a dirt storage cover 251, which is threadedly connected to the outer wall of the sewage discharge pipe 22; a water inlet pipe 252, which is communicated with the surface of the output pipe 21; a first gate valve 253, which is installed inside the water inlet pipe 252; a second gate valve 254, which is installed inside the output pipe 21. Among them, when the second gate valve 254 is closed and the first gate valve 253 is opened, the water supply equipment is connected through the water inlet pipe 252 to inject water into the output pipe 21 to backwash the second filter screen 24. The output pipe 21 and the sewage discharge pipe 22 are fixedly connected by bolts, which is convenient for disassembly and convenient for cleaning the first filter screen 23;

[0025] In the specific implementation process, it is particularly worth noting that when there is too much impurity on the surfaces of the first filter screen 23 and the second filter screen 24, the water supply device is connected through the water inlet pipe 252, the first sluice valve 253 is opened, and the second sluice valve 254 is closed. The water flow of the water supply device flows in the direction of the second filter screen 24 to perform backwashing on the second filter screen 24. The impurities on the surface of the second filter screen 24 fall onto the surface of the first filter screen 23. Then, the sewage discharge pipe 22 is disassembled to wash the first filter screen 23, and the dirt storage cover 251 stores the filtered impurities;

[0026] Furthermore, a flange 13 is installed at one end of the output pipe 21 close to the second sluice valve 254;

[0027] In the specific implementation process, it is particularly worth noting that the adapter body 1 is installed through the flange 13;

[0028] Specifically, when using this anti-blocking fire pump adapter, after the adapter body 1 is connected, the water flow passes through the adapter body 1 and flows into the output pipe 21, and then continues to flow into the sewage discharge pipe 22. The first filter screen 23 inside the sewage discharge pipe 22 blocks the impurities. Then, it will continue to flow along the other end of the output pipe 21 and is then blocked by the second filter screen 24 for the second time, preventing too many impurities from blocking the adapter body 1. The second filter screen 24 can be backwashed through the backwashing part 25 to prevent too many impurities on the second filter screen 24 from affecting the filtering effect. Due to the bolted connection relationship between the sewage discharge pipe 22 and the output pipe 21, it is convenient to disassemble, and the first filter screen 23 can be disassembled and cleaned. When there is too much impurity on the surfaces of the first filter screen 23 and the second filter screen 24, the water supply device is connected through the water inlet pipe 252, the first sluice valve 253 is opened, and the second sluice valve 254 is closed. The water flow of the water supply device flows in the direction of the second filter screen 24 to perform backwashing on the second filter screen 24. The impurities on the surface of the second filter screen 24 fall onto the surface of the first filter screen 23. Then, the sewage discharge pipe 22 is disassembled to wash the first filter screen 23, and the dirt storage cover 251 stores the filtered impurities. The adapter body 1 is installed through the flange 13.

[0029] Embodiment Two: As Figures 1-4 It can be seen that an anti-flow unit 3 is arranged inside the adapter body 1. The anti-flow unit 3 includes: a valve stem nut 31, fixedly connected to the bottom of the valve cover 12; a valve stem 32, threadedly connected to the inner wall of the valve stem nut 31 and penetrating through the top of the valve cover 12; a handwheel 33, fixedly connected to one end of the valve stem 32 outside the adapter body 1; a valve flap 34, fixedly connected to the bottom of the valve stem 32; and a sealing rubber pad 35, covering the bottom of the valve flap 34. Among them, the valve stem 32 and the valve flap 34 are lifted and adjusted by rotating the handwheel 33, and the sealing performance of the adapter body 1 when it is closed is ensured through the sealing rubber pad 35;

[0030] In the specific implementation process, it is worth particularly pointing out that the valve stem 32 and the valve flap 34 are lifted and lowered through the handwheel 33. When water flow is required, the valve flap 34 is moved upward. When backwashing the second filter screen 24 is required, the valve flap 34 is pressed tightly against the top inner wall of the adapter body 1. The sealing rubber gasket 35 ensures the sealing performance when the adapter body 1 is closed, ensuring that the water flow of the water supply equipment does not flow into the interior of the adapter body 1;

[0031] Furthermore, a safety valve 4 is installed on one side of the adapter body 1. The model of the safety valve is not specifically described here;

[0032] In the specific implementation process, it is worth particularly pointing out that the safety valve 4 functions to open when the pressure inside the adapter body 1 is too high, and can timely relieve the pressure inside the adapter body 1 to avoid damaging other parts inside the adapter body 1;

[0033] Specifically, based on the above-mentioned first embodiment, the valve stem 32 and the valve flap 34 are lifted and lowered through the handwheel 33. When water flow is required, the valve flap 34 is moved upward. When backwashing the second filter screen 24 is required, the valve flap 34 is pressed tightly against the top inner wall of the adapter body 1. The sealing rubber gasket 35 ensures the sealing performance when the adapter body 1 is closed, ensuring that the water flow of the water supply equipment does not flow into the interior of the adapter body 1. The safety valve 4 functions to relieve the pressure in a timely manner when the pressure inside the adapter body 1 is too high, avoiding damaging other parts inside the adapter body 1.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
